I receive a ton of calls for advice on which lab to choose. I typically answer their questions, with my own questions. I will ask them:
It makes for a less complicated calving season if you make sure to have all of your animals on file at one lab. Both labs will accept the genetic marker test (and any genotype test), from the other lab, for a small transfer fee.
Below you will see in the picture below, that our pedigree sight has the lab number listed for this heifer. She was tested at UC Davis. This is a fairly recent addition to our pedigree site, so you will likely not find this information if the Dexter is older than a couple of years. CLICK HERE to go to the pedigree site to search your Dexters. Again, you may not see a lab number if the Dexter is older.
